Title : Tillage affects the soil properties and crop yields Material Type: printed text Authors: T Karki, Author ; Shrestha, J., Author Pagination: 432-438 p. Languages : English (eng) Keywords: Conservation tillage, soil properties, yields. Abstract: With the aim of consolidating the information of soil tillage and its effect on soil properties and crop yields, a brief review of the works being done within and outside the country was carried out. The review revealed that conventional agriculture system with intensive tillage practices deteriorated the soil quality and affected the crop yields. Tillage decreased the soil organic carbon, the crucial store house of soil-plant system and the major nutrient nitrogen over longer run. Conservation tillage (CT) also called the minimum or no tillage where soil is covered with crop residue, significantly improved the physical, chemical and biological properties of soil. CT increased the soil aggregates of more than 2 mm by 134%, increased water availability by 36-45 %, and porosity. Similarly, higher thermal conductivity in CT soils produced the lower increase in soil temperature in the upper soil profile. In CT, soil pH was higher in surface but lower in sub surface………………….

in Proceedings of the 28th National Winter Crops Workshops held at Lumle, 9-10 March 2011 / Giri, Y.P.
Title : Evaluation of different methods of wheat establishment under excessive moisture condition Material Type: printed text Authors: Khan, S.U., Author ; N.K Bista, Author ; J.P.L Shrivastav, Author ; G.P Paudel, Author Pagination: 254-257 p. Languages : English (eng) Keywords: Zero Tillage, Relay Planting Abstract: Farmers are experiencing labor and time shortage during wheat sowing as there is less turnaround time between rice harvest and wheat sowing. This study was conducted to find out alternative of traditional tillage method of wheat sowing. Traditional tillage method, relay, surface, zero tillage and power tillage wheat sowing were evaluated. Alternate wheat sowing has created better conditions for water and weed control and allows 20-30 days earlier sowing of wheat and reduced the inherent drudgery in traditional wheat sowing. Farmer's tillage practice is labor intensive, costly and requires about 5-6 times plowing at sowing time and often result in delay sowing of wheat. Mean wheat grain yield under relay, surface, power tillage and zero tillage was more (about 21%) than farmer's tillage method.........................
